With 4-nitrobenzylphosphonic acid and 2,2-dimethyl-1,3-propanediol, the same procedure as in Reference Example 11 was followed, to yield 5,5-dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinane-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless plates having a melting point of 176° to 177° C.
